Burner of Gas Grill

ABSTRACT

A gas grill includes burners, distributors and a grid. Each of the burners includes a middle section formed between two terminal sections. At least one of the terminal sections includes two rows of outlet apertures. The middle section includes a single row of outlet apertures. Each of the distributors is provided over a corresponding one of the burners. The grid is located over the distributors.

BACKGROUND OF INVENTION

1. Field of Invention

The present invention relates to a gas grill and, more particularly, to a burner of a gas grill.

2. Related Prior Art

A conventional burner includes a middle section formed between two terminal sections. The burner includes two opposite rows of outlet apertures. Gas vents from the outlet apertures while traveling along the burner, from one of the terminal sections to the other terminal section via the middle section. The gas is ignited to provide fire. An amount of gas venting from each of outlet apertures in each of the terminal sections is expected to be identical to an amount of gas venting from each of the outlet apertures in the middle section. However, in practice, the amount of gas venting from each of the outlet apertures in each of the terminal sections is smaller than the amount of gas venting from each of the outlet apertures in the middle section. Hence, the fire along each of the terminal sections is smaller than the fire along the middle section, and this is not desirable.

The present invention is therefore intended to obviate or at least alleviate the problems encountered in prior art.

SUMMARY OF INVENTION

It is the primary objective of the present invention to provide a gas grill with burners for providing heat evenly.

To achieve the foregoing objective, each of the burners includes a middle section formed between two terminal sections. At least one of the terminal sections includes two rows of outlet apertures, and the middle section includes a single row of outlet apertures.

Other objectives, advantages and features of the present invention will be apparent from the following description referring to the attached drawings.

BRIEF DESCRIPTION OF DRAWINGS

The present invention will be described via detailed illustration of the preferred embodiment referring to the drawings wherein:

FIG. 1 is an exploded view of a gas grill provided with burners in accordance with the preferred embodiment of the present invention;

FIG. 2 is an exploded view of one of the burners shown in FIG. 1;

FIG. 3 is a cross-sectional view of one of the burners illustrated in FIG. 2; and

FIG. 4 is another cross-sectional view of the burner shown in FIG. 2.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

Referring to FIG. 1, a gas grill is provided with several burners 10 in accordance with the preferred embodiment of the present invention. Each of the burners 10 is a tubular element that includes a middle section 12 formed between two terminal sections 14 and 16. The terminal section 14 of the burner 10 is connected to a front portion of the gas grill while the terminal section 16 of the burner 10 is connected to a rear portion of the gas grill. A distributor 20 is preferably provided over each of the burners 10. A grid 22 is provided over the distributors 20.

Referring to FIGS. 2 through 4, each of the burners 10 includes a single row of outlet apertures 18 in the middle section 12 and two rows of outlet apertures 18 in each of the terminal sections 14 and 16. In the middle section 12 of the burner 10, the single row of outlet apertures 18 is located on the top. In each of the terminal sections 14 and 16, the rows of outlet apertures 18 are located on two opposite flanks.

In operation, gas is transferred into the burner 10. The gas vents from the burner 10 via the outlet apertures 18 while traveling along the burner 10, from the first terminal section 14 to the terminal section 16 through the middle section 12. The gas is ignited to provide fire to provide heat to cook.

A portion of the gas venting from each of the outlet apertures 18 in the middle section 12 of the burner 10 is larger than a portion of the gas venting from each of the outlet apertures 18 in each of the terminal sections 14 and 16 of the burner 10. An average amount of gas venting from the middle section 12 of the burner 10 is however a little smaller than an average amount of gas venting from each of the terminal sections 14 and 16 of the burner 10 since there is only one row of outlet apertures 18 in the middle section 12 of the burner 10 while there are two rows of outlet apertures 18 in each of the terminal sections 14 and 16. The average amount is defined as the total amount divided by the length. Hence, the fire is a little smaller along the middle section 12 of the burner 10 than along each of the terminal sections 14 and 16 of the burner 10. The difference is however small and easily eliminated by the distributor 20, which distributes the heat so that the temperature is substantially constant along the corresponding distributor 20. Therefore, the temperature is substantially constant all over the grid 22.

The present invention has been described via the detailed illustration of the preferred embodiment. Those skilled in the art can derive variations from the preferred embodiment without departing from the scope of the present invention. Therefore, the preferred embodiment shall not limit the scope of the present invention defined in the claims. 

1. A burner comprising: two terminal sections, wherein at least one of the terminal sections comprises two rows of outlet apertures; and a middle section formed between the terminal sections and made with a single row of outlet apertures.
 2. The burner in accordance with claim 1, wherein each of the terminal sections comprises two rows of outlet apertures.
 3. The burner in accordance with claim 1, wherein the two rows of outlet apertures are located on two opposite flanks of the terminal section.
 4. The burner in accordance with claim 1, wherein the single row of outlet apertures is located on a top of the middle section.
 5. A gas grill comprising: burners each comprising two terminal sections and a middle section formed between the terminal sections, wherein at least one of the terminal sections comprises two rows of outlet apertures, and the middle section comprises a single row of outlet apertures; distributors each provided over a corresponding one of the burners; and a grid provided over the distributors.
 6. The gas grill in accordance with claim 5, wherein each of the terminal sections comprises two rows of outlet apertures.
 7. The gas grill in accordance with claim 5, wherein the rows of outlet apertures are located on two opposite flanks of the terminal section.
